The filtration industry plays a pivotal role in enhancing the quality and safety of products across various sectors, from pharmaceuticals to water treatment. It encompasses innovative technologies and materials designed to remove impurities and contaminants, ensuring compliance with health standards.
In this blog, we will delve into the significance of stainless steel filter cartridge housings, showcasing their functionality, material composition, applications, and the unique advantages they offer in diverse industrial filtration processes.
Stainless steel filter cartridge housings are critical components in the filtration process that house filter elements, which may be in the form of bags, cartridges, or in another form. The MOC being stainless steel, the housings are resistant to corrosion from humid/aqueous environments. Their robust construction provides strong resistance to both acids and alkalis, depending on the chemistry of the incoming slurry to be filtered.
1) Its primary role is to support the filter media to ensure effective removal of impurities, solids, debris, sediments, or contaminants from fluids or gases. Proper fitting of filter media is crucial. If the dimensional tolerances on the fitting are not adhered to, the fluid can bypass the filter, thus making the filter useless even if the media itself is integral.
2) The structural integrity provided by the SS housing extends the filter's lifespan that results in reliable and efficient filtration performance over time. Stainless steel is resistant to corrosion when compared to carbon steel. Hence, these housings can last for even a decade when used properly. Different stainless steels have been elaborated on in the next section.
3) The housing has to be designed as per process parameters given by the client. The housing should not create excessive pressure drop, when the client uses it for the intended flow rate.
4) The housing should be safe to use, i.e., it has to be designed for pressures higher than the intended usage pressure.
5) The housing should be designed such that its operation is made hassle-free for the technicians who actually are involved in its operation.
The construction of cartridge filter housings can vary, utilizing materials such as SS 304, SS 304L, SS 316, SS 316L, and Carbon Steel, amongst others. Stainless steel variants, especially SS 304 and SS 316, are preferred for their distinct characteristics. SS 304 offers excellent corrosion resistance and ease of sanitation, making it suitable for a wide range of applications. SS 316, with its composition of chromium, nickel, and molybdenum, provides superior strength and corrosion resistance, particularly against chlorides and chlorinated solutions. Both materials are commonly used.
The coatings applied to stainless steel filter cartridge housings are engineered to enhance their durability and resistance to corrosive environments. By selecting the appropriate coating, the lifespan of the housing is significantly extended for continuous performance in harsh industrial conditions without degradation of the base material.
Some of the coating materials include:
a) ETFE (ethylene tetrafluoroethylene)
b) Halar (Ethylene ChloroTrifluoroethylene)
c) PFA (perfluoroalkoxy alkanes)
d) PP (Polypropylene)
